I must say it would have been nice if you had compared this to the HSPC Tech station, which is cheaper, plastic (special insulation material), and just plain simpler (which is good).
There is no need to any screws (at least I don't bother with them). It is taller, which means you can stack more components.

Since you reviewed the Cooler Master, would you have a go at the HSPC, too?

I thought the review was good; comprehensive and explanatory, which is what a review should be, right?

That there's no manual included is no surprise to me, as things should be pretty clear to folks who tend to use these set-ups for testing.

The complaint about the rudimentarity and the fact that the rig hasn't space for a second hard drive, to me doesn't hold ground, because the rig is for testing/overclocking purposes, so, how many discs do you want to hang onto a test set-up? Granted, if/when you would be testing a new PSU, a multi disk set-up could come in handy. But then again, if the discs are already built into the case, it could prove easier to just connect the new PSU to the computer harbouring the discs, instead of disassembling your computer to connect the lot to the testing rig...

having space for multiple disks does come in handy, especially for benchmarks, some apps work better under a certain OS, with multiple disks installed you don't need to swap them out, just connect the sata/power plug differently

@Faiakes: we have another test bench incoming for review, not a HSPC though
